� <br /> � MORTARED APPLICATIONS <br /> � Saturate-concrete subbase with clean water several hours before placing setting-bed. Remove <br /> surface water about 1 hour before placing setting-bed.. <br /> A�ly cement}�aste slush coat over surface of concrete subbase about 15 minutes prior to placing <br /> , sethng-bed. Limit area of slush coat to avoid its drying out p�or to placing setting-bed. Do not <br /> eaceed 1/16 inch thickness for cement slush coat. <br /> , ��,v mortaz settin�-bed over cement paste slush coat immediately after latter has been applied. <br /> Spread and screed setting bed to uniform thickness at subgrade elevations required for accurate <br /> setting of brick to fuushed grades indicated. <br /> ' . Mix and�lace only that amount of mortaz setting bed that can be eovered with brick prior to <br /> initial set. Cut back,bevel edge,remove, and discazd setting bed material that has reached initial <br /> ' set prior to placing brick. <br /> Wet bnck pavers several hours before laying unless their initial rate of absorption(suction)when <br /> subjected to testing by method described in Section 9 of ASTM C 67 is less than 3/4 oz.per 30 sq. <br /> ' inches of unmersed azea. Do not lay brick pavers with free moisture on the surface. <br /> Place brick}�avers before initial set of cement occurs. Inu�ediately prior to placing brick on green <br /> ' or wet setting bed, apply uniform 1/16-inch thick slurry bond coat to bed or to back of each brick <br /> with a flat trowel just prior to plaeing it on bed. <br /> Tamp and beat brick avers with a wooden block or rubber mallet to obtain full contact with <br /> � �setting bed and to bring finished surfaces within indicated tolerances. Set each brick in single <br /> operation prior to initial set of mortaz; do not return to areas already set and disturb bricks for <br /> purposes of realignirig finished surfaces or adjusting joints. <br /> , �rout joints as soon as possible after initial set of setting bed. Force grout into joints,taking caze <br /> not to smeaz grout on adjouung brick and other surfaces. After initial set of grout,finish joints by <br /> tooling to produce a very slightly concave polished joint, free from drying cracks. <br /> � Cure out by maintaining in a condition for 7 days eac t as otherwise recommended b <br /> � � y <br /> latex additive manufacturer. <br /> � - REPAIR�POINTING�CLEANING�AND PROTECTION <br /> � Remove and re�lace unit�avers that are loose,chipped,broken, stained,or otherwise damaged or <br /> if units do not match adjoining units as intended. Provide new units to match adjoining units and <br /> install in same manner as original units,with same joint treatrnent to eliminate evidence of <br /> i replacement. <br /> Pouitin¢: Duruzg tooling of joints,enlazge voids or holes and completely fill with mortar or grout. <br /> Point-up joints at sealant-type joints to provide a neat,uniform appearance,properly prepared for <br /> � application of sealant. <br /> I <br /> SECTTON 02515 - iJ1VIT PAVERS <br /> � Page 5 of 6 <br /> , <br />
